Perovskite solar cell combined with graphene electrode for CO2 reduction

The INTEGRO project aims to develop an artificial photosynthesis device, combining a low cost, high
voltage and efficient photovoltaic (PV) cell, based on perovskite technology, with a metal-free electrocatalyst (EC) fabricated using nitrogen doped graphene, in order to create an integrated PV-EC system.

This system powered by solar energy, will be able to operate at low voltages (< 2.4V) and high faradaic efficiencies (> 80%) and will be able to supply enough energy to initiate the CO2 reduction reaction,
reaching a solar to fuel conversion efficiency > 10%

Nina Carretero

Nina M. Carretero (PhD), researcher at Energy Storage group, obtained her PhD in Material Science from the Institut de Ciència de Materials de Barcelona and the Universitat Autònoma de Barcelona (ICMAB-CSIC and UAB) in 2014. The main research topics were synthesis of new hybrid materials, electrochemistry and electrode applications.

Currently, and since 2015 she is researcher in the Institut de Reserca en Energia de Catalunya (IREC), mainly involved in industrial projects related with photoelectrocatalysis (water splitting and artificial photosynthesis). Her main research interests are catalyst synthesis and characterization, optimization and up-scaling of photoelectrochemical setups. She has authored or co-authored 12 articles with more than 200 cites up to now in referred international journals, 2 patents and more than 18 conference contributions (H-index 7).
